I'm using service studio O11, there is a functionality for login page in  login action called Do/Login but it checks with the User table of System which is by default where we can't add or del any col. I tried creating a new entity and creating a custom login page , for validation i tried checking the encrypted password stored in that new table with the password which user entered while logging in. Ofcourse i encrypted it first then checked it. But still there's some issue I don't know. Please let me know, or share the oml file.

Thanks, Tejas.
